Pulsed field ablation: The basics relating to effectiveness, durability, and safety

Pulsed field ablation (PFA) represents an innovative energy delivery approach for cardiac arrhythmia treatment, characterized by a favorable safety profile and effective myocardial lesion formation. It has demonstrated high acute pulmonary vein isolation rates with a reduced incidence of injury to adjacent anatomical structures. Nonetheless, procedure-specific complications such as haemolysis, intravascular gas formation, and coronary vasospasm have been observed and warrant further evaluation. Clinical evidence supports efficacy comparable to conventional thermal ablation in terms of arrhythmia recurrence. Ongoing advancements in catheter engineering, pulse modulation, and multimodal energy strategies aim to enhance lesion durability and transmurality. These developments position PFA as a promising technology in the field of cardiac ablation.
